BOBBIN-H OLDER FOR ROVING-FRAMES.

Application filed July 2, 1919. Serial No..308,105.

To all whom it may concern:

Be it known that I, ARTHUR D. RAMSAY,

a citizen of the United States, residing at Lowell, in the county of. Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Bobbin-Holders for Roving-Frames, of which the following is a specification.

This inventionis a device to be attached towhat are known as card room roving frames and other similar machines.

The operatorof a roving frame receives wooden bobbins upon which roving is wound and places such bobbins on suitable Skewers or otherdevices on what is known as .a creel. The roving ends fromthis creel pass through drawing rollers which are covered with a smooth plate of metal known as a roll cover, thence to the fliers or otherdevices by which the roving is further twisted and wound on to other smaller bobbins.

From time to time, as the bobbins on the,

creel become empty, the operator goes through the recreeling process, which consists' of removing the empty or substantially empty bobbins from the creel and replacing I aide elevation of a modified form of holding -ook,

them by full bobbins.

During thisyrecreeling it becomes necessary to do something with, the emptybobbins, for if they are thrown upon thefloor they are likely to be broken by the operators feet'or by the movement of the trucks,

and they are also dangerous as the operator is likely to slip on them. If they are dropped upon the floor they are likely also to becomesoiled and to pick up floor waste from which they must afterward be cleaned.

As bobbins generally have ahead which i is larger than the body, they have a tend- 1 ency to roll in curves andwill-not stay in place on any smooth surface which hasthe slightest Slope or which is subject toany ar. 1

It is not feasible to provide baskets or ordinaryracks as they would be in the way @and especially would interfere with the operator when doffing, that is, renewing the small filled bobbins on the spindles.

The roll cover is of.- the most convenient form and in the'most convenient position on Y which to place the empty bobbins, but they will not stay inplace onaccount of the fact that it is smooth and. if it is made rough,

with corrugations. pins, Spindles, or such lil e,-:fiy ings and other Waste-will accumulate and it will be difficult to creel, especially without injuring the operators hands.

It is also desirable to have a device which can be moved out of the way when it be-' comes necessary to doff the frame or tooil the rollers, and it is desirable to have a device which can be adapted for use with different sizes and makes ofmachines and of bobbins.

The recreeling takes a relatively small time and I find it desirable to have a device I tion ofpart of a roving frame embodying my invention, the roll stand and other parts 1 being broken away tomore clearly how the construction. Fig. 2 is a detail substantially aiplan view looking from the direction of the arrow in Fig. 1 of part of the. roll cover and of our bobbin holder. vFigs. 3, 4 and '01 are side elevations showing modifications of our device, and Fig. 6 is a perspective View of another modification. Fig. 7 is a In the drawings, 10, 11, 12, 13 and 14 I represent creel bars which Support the skewers 8 which'carry the various bobbins 20,21, 22, each of which is, filled with roving'R, A represents the supporting frame and B represents the drawingrolls, while C represents the roll cover and D represents the fliers which twist and wind the roving B after it passes through the roving rolls B on to the small bobbins F.

G represents the shipper rod, which is 1 generallyin the position Shown, on such frames, and 16 represents a guide rod which is a guide for the roving. ,The above named parts are all old and well known. My bobbin holder, represented complete by H, includes the front bar 80 in the top of which are a plurality of depressions 31 each adapted to support and hold in place such part of a bobbin as 24, 25, 26, as may rest upon it, and the supporting arms 32, .33, 34, which are shown as fixed at one end thereto. The front bar 30 should be rigid.

Each of these supporting arms, as exampled by 32 in Fig; 1,. comprises a neck 40 which is bent upward and fixed at its end in anysuitable manner to thefron tbar 30; a

shank 4:]. and a loop 42. This longitudinal loop at the other end is relatively long and of such size that the shipper rod G can pass loosely through it. Each of such loops is the roll cover by being hooked over a hook, such as 46, fastened to one of the creel bars,

such as 10.

It will readily be seen by examining Figs. l and 2 that bobbins of various lengths can be placed partly on the bobbin holder and partly on the roll cover, and that they will not roll nor slide out of position, while the bobbin holder can be lifted up out of the way of the operator to permit dofiing, oiling, etc. It is also evident that two or more supporting arms can be used. 7

In Fig. 3, I show a modification of the construction wherein the creel bar hook is dispensed'with, thesupporting arms each being made, with a straight shank 50 which is bent around at 51 to form a longitudinal loop about the shipper rod G, such loop being somewhat longer than shown in Figs. 1 and 2. In addition to this, a suitable weight 52 is attached to the back end of each supporting arm so that, when the bobbin holder is pushed back, the weight will overbalance it and tip it up to the position shown by the dotted lines. This construction cannot be used on most frames but may be used in some cases.

Fig. 4; shows another modification in which the supporting arms comprise a straight shank which extends from the back of the roll cover to the shipper rod G,

thence at 61 to form a loop as shown in the other construction. The front bar 62 extends between the supporting arms on a line back of the roll cover so that the bobbins,

v. An objection to this type is that, in order to 1 keep the bobbins from slipping endwise, it is desirable that. the front bar should be slightly higher than the roll cover, and that the head end of a bobbin should rest on and beyond this front bar. To accomplish this in the construction shown in Fig. 4, it is necessary to turn the bobbin around with the end 1n a position which is unnatural for the operator.

In Fig. 5, I show a construction in which the front bar is carried by slides, such as 71, which are-adapted to slide in and out in suitable grooves or passages 72 in a supporting arm, such as 73, which are shown as pivoted on to any suitable part of the frame, such 74, by means of straps 75. Set screws, such as 7 6, permit these slides, and therefor these front bars, to be adjusted and held in position. 4

It will be understood that while I find the shipper rod a very convenient part of the machine on which to hang my bobbin holder, such bobbin holder can'be attached to any other part of the frame, such as 74, provided the supporting arms rest on the roll cover in such manner as to bring the front bar in a position to cooperate therewith preferably so that the depressions therein will be slightly higher than such cover.

Fig. 6 shows a bobbin holder made of one continuous rod of metal, the front bar being so bent as to form depressions 81 and side bars 82 and,83, being bent back upon themselves so as to form longitudinal loops 84 and 85.

In Fig. 7, I show a metal creel bar 90 and a creel bar hook 91 clamped thereto by means of twonuts 93 and 94 screwed upon the threaded shank 95 whereby such hook can be raised or lowered, put in place or removed at will.

I claim:

1. The combination with a rovin frame having a roll cover, of a bobbin hol er havinga plurality of depressions each adapted to support and hold in place part "of a bobbin while the other part of the bobbinrests on the roll cover, and so hung from the frame that it can rest on or can be moved and held away from the roll cover at will.

'2. The combination with a roving frame having a roll cover, of a bobbin holder which comprises a front bar having a plurality of depressions each adapted to support and I hold in place part of a bobbin while the other part of the bobbin rests on the roll cover, and supporting arms for said front bar so formed and attached to the frame that they can rest on the roll cover or that they can be moved away and held away therefrom.

3. The combination in aroving frame having a roll cover, of a bobbin holder which comprises a front bar having a plurality of depressions each adapted to support and hold in place part of a bobbin and supporting arms fixed at one end to said front bar and bent at the other end to form a longitudinal loop.

4:. The combination with a roving frame having a roll cover, of a bobbin holder which comprises a front bar having a plurality of depressions each adapted to support and hold in place part of a bobbin'while the other part of the bobbin rests on the roll cover, and supporting arms for said front bar so formed and attached to the frame that they can rest on the roll cover or that they can be movedaway and held away therefrom, together with means for holding such bobbin holder away from the roll cover.

5. A bobbin holder for roving frames comprising a relatively rigid front bar having a plurality of depressions each adapted to receive part of a bobbin, and two or more side bars made of elastic metal each fixed at one end to the front bar and each bent around and back on itself at the other end to form an open longitudinal loop.

6. The combination with a roving frame having a roll cover, of a bobbin holder which comprises a front bar adapted to support and hold in place part of a bobbin while the other part of the bobbin rests on the roll cover, and supporting arms for said front bar so formed and attached to the frame that they can rest on the roll cover or that they can be moved away and held away therefrom.

In testimony whereof I have affixed my signature. 7
